SEPARABLE FASTENER.

Specification of Letters Batent.

Patented June 20, 1916.

Application filed April 12, 1915. Serial No. 20,825.

To all whom it may concern:

Be it known that I, GEORGE C. VANMEER, subject of the King of England,residing at Burks Falls, in the Province of Ontario, Dominion of Canada,have invented certain new and useful Improvements in SeparableFasteners; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to a separable fastenor.

An object of the invention resides in the provision of a fastener, theparts of which may be quickly secured together.

A further object of the invention resides in so constructing the devicethat when the two parts are interengaged they will be antomaticallylocked in such position.

A further object of the invention resides in making the fastener so thatone of the members will be adjustable within the other.

A still further object of the invention resides in so constructing thedevice that it will be neat and of such formation as to be particularlyadapted for securing the two parts of a rubber or other shoe together.

With these and other objects in view, such as will appear as thedescription progresses, my invention comprises the combination andarrangement of parts as set forth in and falling within the scope of theappended claim.

Referring to the drawing: Figure 1 is a plan View of my device lookingat the side on which the spring is located. Fig. 2 is a longitudinalsectional view. Fig. 3 is a side elevation. Fig. I is a section on line4-4 of Fig. 1.

Referring to the drawing wherein like parts are indicated by likecharacters throughout the several views: In the embodiment of myinvention shown in the drawings, I have provided a plate 1 which iscurved from end to end and has a loop 2 formed on one end thereof.Extending longitudinally of the plate 1 is a housing 3 which is formedby depressing a portion of the plate. Secured to the plate 1 is aU-shaped spring 4 which is attached, as at 5, and lies in slight spacedrelation to the face of the plate. The bight portion 6 of this springbridges the housing 3 in the manner clearly illustrated in the drawing.The other member of the fastener includes a bar 7 on one end of which isformed a loop 8. Formed on this bar 7, at spaced intervals, areprojections 9 which are inclined toward the loop 8. The body portion ofthe bar 7 is of such dimensions that it will lie entirely beneath theplane of the plate 1 and within the housing 3. The upper ends of the projections 9 will extend above the plane of the plate 1.

When it is desired to secure the two members of the fastener together itis only necessary to push the bar 7 inwardly into the housing 3 at whichtime the bight portion 6 of the spring 4: will ride up on the inclinedface of each successive projection 9 and will drop in behind theprojection. This movement may be continued until the bar 7 has beenpushed into the housing 3 to a sufficient extent. It will be thus seenthat the bight portion 6 of the spring 4, engaging one of theprojections 9 will prevent the disengagement of the members of thefastener without the manual actuation of the spring. The spring,however, will allow the fasteners to be pushed together to any degreeand will automatically lock them in such position.

From the foregoing description it will be seen that I have provided aseparable fastener which is of very simple construction and yet onewhich will be exceedingly useful and which is of such construction thatthe parts are not likely to get out of order.

While I have illustrated and described a particular embodiment of myinvention, I have merely done so for the sake of convenience and I donot wish to be limited to that particular embodiment as it is obviousthat numerous changes may be made within the details of constructionthereof without in any way departing from the spirit of the invention orwithout exceeding the scope of the appended claim.

What I claim is In a separable fastener, the combination with a platehaving a longitudinally extending channel formed by a depressed portionof the plate, of a bar slidably mounted in the channel and having teeththereon adapted to extend outwardly beyond the face of the plate, thebody of the bar being adapted to be located entirely within the channel,and a U-shaped spring detent having its leg portions hinged to the plateand its bight portion bridging the channel and adapted toengage'b'etiveen the teeth on thhzir, the p0r- TiiteStmiohyWheredffInififi' inj'r signa- {glen of the spring Which engages theteeth ture, inlthe presence of two Witnesses.

ein smooth and free from 'ro'ectin )arts r I and having its uppeneclgeacl pt clto-li e flush v V p H 'GEORGE VANMEER' with the edges of theteeth, the legs of the VVitnes'ses: detent lying in slight spacedrelation to the ELIZABETH M. WEIs, plate throughouttheir entire length.GEORGE FREEMAN.
